4 tons 9k

[chuck estevez]

4k open means that 36k btu will do 9 lights non air cooled. Wrong

ok, Ill just take my Ac contractors license and be wrong,lol

Insulation and build of the room has nothing to do with it though


maybe you can explain how I built my buddies rooms with 18 gavitas each and they are cooled by 5 ton a/c units?

 

[patrickkawi37]

Yes, thats what I've been told. 6k btu per non air cooled.

I am getting away with 5k btu per non aircooled
Right now but my box is overkill insulated . No way in hell 4k btu per would work and I'm

they must be exhausting air.... And they definitely aren't running burners. House units might work more efficient. But my buddy just set up 10 gavitas and is using a 5 ton so I don't believe you

I think he's just trying to be helpful. Like making sure your safe with temps.

You can get away with it. But can they get temps down to 68-70 for the last week with lights on? Be pushing it in the summer.

I know someone who runs 12k for 4 thousand watts. Gets away with it but has no control at all. He sets his split to 72, stays 72 with the lights off, and runs full blast with lights on to keep it 80 degrees at the best.

he runs c02, on the bottle, which requires higher temps anyway, and no, probably not going to see 68-70 with the lights on.

 

[a mongo frog]

I wouldn't take a crop to 68 or 70 with lights on. I missed something i think.

I run that temp for lights off. I set my on for 80 and it runs about 82 with c02 supplemented.

Me too pretty much exactly.

I don't fuck around with 80s at all. 78 at the canopy , 76 ish in the room . All my strains taco at 80 degrees . Different strokes for different folks. I bought a 3 ton Ac cause some jackass told me it would do 9 lights not aircooled . My room couldn't keep up. 78.. Then 80.. Then 82.. By end of night closer to 84-85. So I had to get two 2 tons. Quite a fucking setback id say. I didn't cheap out on anything my room is over the top as far as insulation and the build. So when you are saying that 4k Btus per non aircooled is fine... Maybe for a hobbyist who isn't trying to control his temps.. But that would be the only case

are you supplementing c02? if so, you need to be higher temps for it to do anything, if not, then you are exchanging air, which would make a a/c work really hard.

I am not exchanging air. And I am using co2 at 1500ppm. My plants DO NOT like the 80s. This is different with some strains in different rooms. I think the co2 is working just fine considering the yields

@Dr.Who posted a very good article on c02 and how it does nothing at higher levels UNLESS you run the proper temps.

Photosynthesis consists of chemical reactions. Chemical reactions procede at a higher rate at higher temperatures. The rule of thumb is that there is a doubling of the reaction rate for every 10°F rise in temperature. Plants grow faster at a higher temperature providing they have adequate levels of CO2, water, sunlight and plant nutrients. The C4 plants have a great response rate for a higher temperature than does the C3 plants.

A higher temperature without adequate level of the necessary ingredients for growth might produce no response or even damage. Sylvan Wittwer, quoted above, states that under most circumstances the availability of CO2 is the factor which limits growth. Thus with a higher level of CO2 in the air plants can grow faster with a higher temperature.

Plants transpire water vapor to keep an even temperature. There are tiny holes on the underside of plant leaves, called somata, which are the openings through which the plant absorbs CO2. With higher level of CO2 concentration in the air the somata do not have to be open as wide. The narrower opening means that less water is transpired and thus less water is required by the plants. In other words, higher levels of CO2 increase the efficiency of water use by plants. This was confirmed in experiments reported by K.E. Idso and S.B. Idso. They found that enhanced CO2 increased growth by 31 percent in plants with adequate moisture but it increase growth by 62 percent for plants in moisture-stressed condition. In effect, enhanced CO2 by reducing water loss created the same effect as providing more water. Thus the effect in moisture-stressed plants was the effects of enhanced CO2 plus the effect of increased water.

The effect of increased CO2 in narrowing the stomata of plants has the additional benefit that a lesser amount of pollutants in the air will make it through the narrower openings. Thus enhanced CO2 has the effect of protecting plants against damage from air pollutants such as ozone or sulfur dioxide.

The effect of enhanced CO2 is even greater for plants grown under low light conditions. The enhance growth is greater than 100 percent for a 100 percent increase in CO2. This compares to less than 50 percent for plants grown in normal light conditions.

The evidence that clinches the argument is that some greenhouse owner artificially elevate the CO2 level to triple what the level in the atmosphere is.

I don't even need to read this. To possibly suffer quality because of heat stress and get hairy booboo nugs that I can't move to my patients .. Not an option .. For what? A higher yield ? I'm not trying to be big headed but I knock it out of the park pretty much every time . I don't need a bigger yield if it was to suffer quality . I've grown nugs in the 80s, it's great medicine , but I think the plant gets stressed out and you lose quality and bag appeal . This is my opinion, you have yours .

People around here like to finish in cold temperatures. Brings out colors that wouldn't have happened without the cold.

Since you have the expertise, I'd like you to explain that to me, actually. Is that half and half on a flip? Sealed hoods?

2 rooms, each runs 12 hrs a day, each has it's own 5 ton a/c unit. Not too hard to understand, standard open hood gavitas

you don't have to raise your temps, but you could do your wallet a favor by not running those unnecessary 1500 ppms
if you don't match the temps to the ppms, it's just a waste.

I'm cooling 18kW with 4 Tons. Bare bulbs, every last one of them.

so you are cooling 18 open 1000's with a 4 ton? and this guy is telling me bs on a 5 ton for 18,lol

or are you running 9 and 9 on a flip?

I have built rooms with 1, 5 ton unit on a zone control and as soon as the lights go off in 1 room, the other comes on and the air is transfered to that room
